Description
Technical field
The present invention relates to a kind of upper turning-up devices, it is specifically a kind of on furniture turning-up devices it is adjustable on turn over Labor saving machine
Structure.
Background technology
Chinese patent literature number discloses a kind of Upturning door hinge on November 16th, 2011 for CN202039710U, the structure
The curved end of the first cursor is rotatably connected with substrate, and curved end and the substrate of the second cursor are rotatably connected, can be simultaneously
The two ends of the above-mentioned linking arm together with being coincided with the first cursor, the respective straight end of the second cursor are rotated with first respectively
Arm, the respective straight end of the second cursor are rotatably connected, and linking arm is located between the first cursor, the second cursor, first turn
The curved end of swing arm is hinged with the free end of the motion bar of gas bar, and the fix bar of gas bar is operatively connected on substrate, and substrate is also
It is provided with elastic devices with impact portions, after the second cursor is rotated with the corner elastic collision.It is said that the structure can
To reduce noise, the closing motion or open motion of cabinet door is more flexible, and cabinet door, in motor process, is integral translation campaign
, common cabinet door can be avoided to collide the situation of head；But, the Upturning door hinge only realizes buffering resistance by elastic device
Power when Buddhist nun, closing motion or open motion is unable to reach uniform effect, and the elastic device is hinged opening and closing in tilt-up door
When frictional force it is big, high noise, tilt-up door again can be because deadweight reason be automatically switched off, also without adjusting work(after opening certain angle
Can, it is impossible to meet the use demand of user.Therefore, it is necessary to further improve.
The content of the invention
The purpose of the present invention aims to provide a kind of simple and reasonable, safe and reliable, easily production, easily realizes, adjusts quick,
It is easy to operate, it is laborsaving during opening and closing, smooth, collide the low upper turning-up devices of little, noise it is adjustable on turn over effort-saving mechanism, to overcome
Weak point of the prior art.
By the design of this purpose a kind of upper turning-up devices it is adjustable on turn over effort-saving mechanism, including retaining element, linking arm
